Description
RELATED APPLICATION
[0001] This application claims the benefit of U.S. provisional
patent application Ser. No. 60/479,049 filed on Jun. 17, 2003.
BACKGROUND OF THE INVENTION
[0002] Certain vehicles, such as pick-up trucks and sport utility
vehicles (SUV) include cargo areas which are difficult for a user
to access because of the height of the cargo area from the ground.
In the past, different types of steps have been utilized to assist
a user in accessing the cargo areas of such vehicles. A number of
these steps are mounted to the vehicle through the use of the
vehicle's trailer hitch receiver. As the trailer hitch receiver is
in use in this type of step, mounting of the step to the vehicle
prevents the user from towing a trailer using the trailer hitch
receiver when the step is connected to the vehicle.
[0003] Other steps mounted to the vehicle are pivotally connected
to the vehicle allowing the step to move from a horizontal position
in use, to a vertical position when the step is not in use. When
using these types of steps with pick-up trucks, for example, when
the tail gate of the pick up-truck is lowered, the step is
positioned under the tail gate of the pick-up truck and provides no
assistance to the user.
[0004] A disadvantage of providing a step at the rear of the
vehicle is that the step extends rearwardly of the vehicle creating
an obstruction. As a result, additional space is needed to park the
vehicle; one must take care when passing behind the rear of the
vehicle to avoid the step; and when traveling on a road, other
vehicles must avoid the rearwardly extending step which can often
be difficult to see.
[0005] The present invention provides a step assembly which
eliminates or reduces the problems described and provides
additional advantages as will be described herein.
OBJECTS AND SUMMARY OF THE INVENTION
[0006] A general object of the present invention is to provide a
step assembly for allowing easier access to the cargo area of a
vehicle.
[0007] An object of the present invention is to provide a step
assembly which provides easier access to the cargo area of a
pick-up truck when the gate of the pick-up truck is in a lowered
position.
[0008] Another object of the present invention is to provide a step
assembly which allows for use of a trailer hitch assembly when the
step assembly is mounted to the vehicle.
[0009] Yet another object of the present invention is to provide
lighting to the area around the step assembly when the step
assembly is in a generally horizontal or vertical position.
[0010] A further object of the present invention is to provide an
additional brake light for the vehicle to which the step assembly
is mounted.
[0011] Yet a further object of the present invention is to provide
protection for the tailgate or rear of the vehicle from impact.
[0012] Still a further object of the present invention is to
provide security to the tailgate or rear of the vehicle.
[0013] A still further object of the present invention is to
provide a power supply to which electronic accessories can be
attached.
[0014] Briefly, an in accordance with the forgoing, the present
invention discloses a folding step assembly which can be mounted to
a standard trailer hitch receiver. The step assembly is
particularly useful when mounted to pick-up truck or a sport
utility vehicle in that it allows for easier access to the bed of
the pick-up truck or the cargo area of the SUV which are typically
approximately thirty-three (33) inches above ground level. The
height of the step assembly when in the lowered position is
approximately one-half of the distance between the ground and the
bed of the pick-up truck or SUV.

the latch 160 and through the aperture 146 of the latch guide 144
to secure the step in the upright position.
[0058] The front member 88 further includes a right end wall 172,
see FIGS. 4 and 4a, provided proximate the notch 140, 148. The
right end wall 172 abuts the first and third panels 126, 130 of the
front member 88. An aperture is provided through the right end wall
172 and is aligned with the aperture through the left end wall
150.
[0059] As shown in FIG. 3, the rear member 90 extends from the left
support 86 to the right support 84, proximate the rear edges 116,
100 thereof. The rear member 90 includes a front panel 174, a rear
panel 176, a bottom panel 178 and a top panel 180. The front panel
174 is rectangularly-shaped and is spaced from the rear edges 116,
100 of the left support 86 and the right support 84. The bottom
panel 178 is rectangularly-shaped and extends from the left support
86 to the right support 84 proximate the bottom edges 112, 96
thereof and from the front panel 74 to the rear panel 176. The
bottom panel 178 is perpendicular to the front and rear panels 174,
176. The rear panel 176 is rectangularly-shaped and extends from
the left support 86 to the right support 84 proximate the rear
edges 116, 100 thereof and extends from the bottom panel 178 to the
top panel 180. The rear panel 176 is perpendicular to the bottom
panel 178. The top panel 180 is generally rectangular and extends
from the left support 86 to the right support 84 and forward from
the rear panel 176 along the third portions 110c, 94c of the top
edges 110, 94 fo the left and right supports 86, 94. A tread is
provided on the upper surface of the top panel 180 to provide a
skid resistant surface. The tread or skid resistant surface can be
created, for example, by pouched metal, raised diamond plate,
bonded rubber treads, spray-on material or other skid resistant
surfaces.
[0060] As shown in FIG. 2, brake lights 182 are mounted to the
bottom panel 178 of the rear member 90. The brake lights 182 are
spaced apart from each other such that each is proximate an end of
bottom panel 178. The brake lights 182 are connected to electronic
circuitry such that when the brake lights 8 (see FIG. 1) of the
vehicle 12 are illuminated, the brake lights 182 are also
illuminated.
[0061] Step lights 184 are mounted through swivel bases 186 to the
front panel 174 of the rear member 90. The step lights 184 are
spaced apart from each other such that each is proximate an end of
bottom panel 178. The step lights 184 are electrically connected to
a connector which is typically used to provide electrical power to
a trailer, for example. The step lights 184 can be electrically
connected to operate in conjunction with the vehicle's reverse
lights. A switch 188 (see FIG. 2) can also be provided for to
supply power to the lights upon activation of the switch 188 when
the step 18 is in use. The switch 188 can be, for example, a three
way switch. In a first/off position no power is supplied to the
lights 184, in a second/intermediate position the lights 184
operate in connection with the reverse lights of the vehicle to
indicate that the vehicle is backing up. In a third/on position the
lights 184 remain illuminated.
[0062] The cross tube 92 is cylindrically-shaped and extends from
the left support 86 to the right support 84. The cross tube 92 is
spaced from the rear edges 116, 110 of the left support 86 and the
right support 84 and is fixed to the left and right supports 86,
84, for example, by passing fasteners, such as, for example, bolts
190 through the apertures in the left and right supports 86, 84 and
securing the bolts 190 to the cross tube 92. The cross tube 92
could also be welded to the left support 86 and the right support
84.
[0063] As shown in FIG. 3, a pin assembly 192 generally includes a
pin 194, a bent locking wire 196, a spacer 200 and a washer 202.
The pin 194 is generally elongated and includes a first portion
194a, second portion 194b, an elbow 194c, a groove 197 (see FIG.
4a) and a tip 198. The first portion 194a is angled relative to the
second portion 194b, and the elbow 194c is provided between the
first portion 194a and the second portion 194b. The tip 198 is
provided at the end of the second portion 194b opposite the elbow
194c. The groove 197 is spaced from the tip 198. The spacer 200 is
generally cylindrically-shaped and a passageway 204 is provided
through the spacer 200.
[0064] Now that the specifics of the components of the step
assembly 10 have been described, assembly of the step assembly 10
is described. Assembly of the step assembly 10 begins by placing
the shaft 32 of the mounting member 16 into the passageway 28 of
the trailer hitch receiver 14 and aligning the apertures 54 of the
shaft 32 with the apertures 30 of the trailer hitch receiver 14. A
pin is passed through the apertures 54, 30 to secure the shaft 32
within the trailer hitch receiver 14. Next, the step 18 is aligned
with the mounting member 16 such that the shaft 32 is positioned
within the notch 140, 148 of the front member 88 of the step 18.
The aperture 60 through the left side plate 34 of the mounting
member 16 is aligned with the aperture through the left end wall
150 of the front member 88 of the step 18, and the aperture 72
through the right side plate 36 of the mounting member 16 is
aligned with the aperture through the right end wall 176 of the
front member 88 of the step 18.
[0065] The tip 198 and groove 197 of the pin 194 are then passed
through the aperture through the left end wall 150, through the
passageway 204 of the spacer 200, through the washer 202, through
the aperture in the left side plate 34, under the shaft 32 of the
mounting member 16, through the aperture 72 in the right side plate
36, and through the aperture through the right end wall 172. The
locking wire 196 is then placed in the groove 197 to secure the
step 18 to the mounting member 16. After assembly of the step 18
with the mounting member 16, the electrical connections are made
between the wiring provided on the vehicle 12 and the brake lights
182 and step lights 184 of the step 18.
[0066] As shown in FIG. 6a, when the step 18 is assembled with the
mounting member 16, the first end 64 of the flange 62 abuts the
flat surface 168 of the free end of the second portion 160b of the
latch 160, such that the step 18 is in an upright or vertical
position and to prevent the step 18 from being rotated to the
lowered or horizontal position. With the step 18 in the upright
position, the top panel 180 of the rear member 90 is positioned
higher than and above (i.e. over) the bumper 6 of the vehicle 12
and the bumper 6 is positioned within the curvature of the second
portions 110b, 94b of the top edges 110, 94 of the left and right
supports 110, 94. The curvature of the second portions 10b, 94b
allows the top panel 180 to be positioned closer to the tailgate 4
of the vehicle 12 by utilizing the space above the bumper 6 of the
vehicle 12 when the step 18 is in the upright position. The
anti-racking bumpers 108, 124 contact the bumper 6 of the vehicle
and are slightly compressed. The anti-racking bumpers 108, 124
serve to dampen road vibrations and to remove any play between the
step assembly 10 and the vehicle 12.
[0067] As shown in FIGS. 4a and 5, with the step 18 in the upright
position, the lock aperture 146 of the latch guide 144 is aligned
with the lock aperture 162 of the latch 160. A lock, such as a
padlock, can be mounted through the lock apertures 146, 162 to
secure the step 18 in the upright position. With the step 18
secured in the upright position, additional security is provided to
the cargo area 2 of the pick-up truck 12 as the step 18 will
prevent the tailgate 4 of the vehiclel 2 from being lowered to its
open position. In addition, protection is provided to the tailgate
4 or rear door of the vehicle 12 because the step assembly 10 will
be impacted by an outside object before the tailgate 4 or rear door
of the vehicle 12 is impacted.
[0068] With the step 18 in the upright position, the brake lights
182 are directed rearwardly. Upon illumination of the brake lights
8 of the vehicle 12, the brakes lights 182 of the step assembly 10
will also illuminate to provide additional visual warning to
following drivers that the vehicle 12 is stopping. If the switch
188 is positioned in the second/intermediate position, when the
vehicle 12 is placed in reverse, the step lights 184 will
illuminate.
[0069] In addition, with the step 18 in the upright position,
portions of the step 18 extend in the forward direction. As a
result, the top panel 180, a portion of the step 18 is positioned
above a portion of the bumper 6, i.e. a portion of the step 18 is
positioned higher than and in front of the rear most portion of the
bumper 6.
[0070] Finally, mounting of the step assembly 10 to the vehicle 12
does not prohibit access to the ball assembly 78. Rather the ball
assembly 78 can be accessed and articles can be towed using the
ball assembly 78 without the need to remove the step assembly
10.
[0071] To lower the step assembly 10, the lock 63 is first removed
from the latch guide 144 and the latch 160, the user grasps the
first portion 160a of the latch 160. The user can lower the step 18
using one hand by pulling the latch 160 upward. As the latch 160 is
pulled upward, the spring abutment 165 compresses the spring 164,
until the tip 170 of the second portion 160b of the latch 160
contacts the outer surface of the flange 62. The user then releases
latch 160 and rotates the step 18 away from the vehicle 12. The
step 18 is rotated about the pin 194. The tip 170 of the latch 160
slides along the outer surface of the flange 62 until the tip 170
reaches the second end 66 of the flange 62, as shown in FIG. 7a.
The step 18 will rotate approximately ninety degrees to reach the
lowered position as shown in FIG. 7.
[0072] With the step 18 in the lowered position, the stepping
member 180 of the rear member 90 extends horizontally and
rearwardly beyond the lowered tailgate 4 of the vehicle 12. The
stepping member 180 provides a surface preferably approximately
twenty-seven inches wide by twelve inches deep. The user can step
on the stepping member 180 to assist in loading items into the bed
or cargo area 2 of the vehicle 12. Preferably, the height of the
stepping member 180 of the step 18 is approximately one-half of the
height from the ground to the bed or cargo area 2 of the vehicle 12
or approximately sixteen and one-half inches from the ground.
[0073] With the step 18 in the lowered position, the user can
activate the switch 188 and the step lights 184 will illuminate the
ground in the area surrounding the step 18 to provide greater
visibility to the step 18 and the surrounding area. In addition,
the swivel mounts 186 allow the user to position the lights 184 and
direct the lights 184 as desired.
[0074] To raise the step 18 to the upright position, the user can
simply grasp the rear member 90 and rotate the step 18 about the
pin 194. As the user rotates the step 18, the tip 170 of the latch
160 slides along the outer surface of the flange 62 until the tip
170 reaches the second end 66 of the flange 62. The beveled surface
166 of the latch 160 allows the tip 170 to easily slide along the
flange 62. The user continues to rotate the step 18. Upon rotating
the step 18 ninety degrees, when the tip 170 passes the first end
64 of the flange 62, the spring pushes against the spring abutment
165 to force the latch 160 downward, such that the flat surface 168
of the latch 160 will engage the first end 64 of the flange 62 to
secure the step 18 in the upright position as shown in FIG. 6a.
[0075] Mounting of the left and right side plates 34, 36 has been
described such that the pivot pin apertures 60, 72 extend below the
bottom wall 48 of the shaft 32. Alternatively, the left and right
side plates 34, 36 could be mounted such that the pivot pin
apertures 60, 72 extend above the top wall 46 of the shaft 32 when
mounting the left and right side plates 34, 36 in this manner,
assembly of the step assembly 10 results in the pin 194 positioned
above the shaft 32.
[0076] Although the step assembly 10 is shown with a ball assembly
40 which can receive a trailer hitch, the step assembly 10 does not
require the ball assembly 40.
[0077] Attention is now invited to a second embodiment of the step
assembly 200 shown in FIGS. 9-14. The step assembly 200, is mounted
to the rear of a vehicle, such as the vehicle 12 shown in FIG. 1.
As with the step assembly 10, the step assembly 200 is mounted to

angled relative to the second portion 358. The first portion 356 is
generally parallel to the third portion 360.
[0098] The mounting bracket 344 is positioned around the first
portion 356 of the handle 342.
[0099] The first spring 352 is also positioned around the first
portion 356 of the handle 342 and is positioned within the mounting
bracket 344. A spring abutment is fixed to the first portion 356 of
the handle 342 proximate the first spring 352 to compress the first
spring 352 as will be described herein.
[0100] The left spring bumper 346 and the right spring bumper 348
are positioned around the third portion 360 of the handle 342. The
right spring bumper 348 is fixed to the third portion 360 of the
handle 342, while the left spring bumper 346 moves relative to the
third portion 360 of the handle 342. The second spring 354 is also
positioned around the third portion 360 of the handle 342 and is
positioned between the left spring bumper 346 and the right spring
bumper 348.
[0101] The gripping ball 350 is mounted on the outer end of the
third portion 360 of the handle 342.
[0102] The mounting bracket 344 is mounted to the release handle
support member 306 of the shaft brace 82 using, for example, bolts
and nuts. The release handle assembly 340 is aligned with the
remainder of the step 204 such that the handle 342 passes through
the release handle aperture 309 of the left arm 296 of the shaft
brace 282 and through the release handle aperture 276 of the left
support 254.
[0103] Now that the specifics of the components of the step
assembly 200 have been described, assembly of the step assembly 200
is described. Assembly of the step assembly 200 begins by placing
the shaft 206 of the mounting member 202 into the passageway 28 of
the trailer hitch receiver 14 and aligning the apertures 226 of the
shaft 202 with the apertures 30 of the trailer hitch receiver 14. A
pin is passed through the apertures 226, 30 to secure the shaft 206
within the trailer hitch receiver 14. Next, the step 204 is aligned
with the mounting member 202 such that the left side plate 208 of
the mounting member 202 is positioned proximate the left arm 296 of
the shaft brace 282 and the right side plate 210 of the mounting
member 202 is positioned proximate the right arm 298 of the shaft
brace 282. When the step 204 is properly aligned with the mounting
member 202, the pivot pin aperture 302 of the shaft brace 282 is
aligned with the pivot pin aperture 236 of the left side plate 208
and the pivot pin aperture 304 of the shaft brace 282 is aligned
with the pivot pin aperture of the right side plate 210. The pivot
pin 305 is then inserted through the aperture 302 of the left arm
296 of the shaft brace 282, through the aperture 236 of the left
side plate 208 of the mounting member 202, through the aperture of
the right side plate 210 of the mounting member 202, and through
the right arm 298 of the shaft brace 282. The retaining pin 307 is
then inserted through the retaining pin aperture of the retaining
pin 305 to secure the retaining pin 307.
[0104] As best shown in FIGS. 9 and 12, when the step 204 is in the
upright position, the first portion 356 of the release handle 342
is positioned under the shaft 206 of the mounting member 202 and
under the left plate 208 of the mounting member 202. The gripping
ball 350 extends to the left of the left support 254. Contact
between the handle 342, the shaft 206 and the left plate 208,
prevents rotation of the step 204 about the pivot pin 305. Similar
to the step 18, when the step 204 is in the upright position, the
stepping member 322 of the rear member 258 is positioned above the
bumper 6 of the vehicle 12 and the bumper 6 is positioned within
the curvature of the second portions 264b of the top edges 264 of
the left and right supports 254, 252. The curvature of the second
portions 254b allows the stepping member 322 to be positioned
closer to the tailgate 4 of the vehicle 12 by utilizing the space
above the bumper 6 of the vehicle 12 when the step 204 is in the
upright position. Thus, the stepping member 322 is positioned
forward of at least a portion of the bumper 6. The anti-racking
bumpers 310 contact the bumper 6 of the vehicle and serve to dampen
road vibrations and to remove any play between the step assembly
200 and the vehicle 12.
[0105] With the step 204, protection is provided to the tailgate 4
or rear door of the vehicle 12 because the step assembly 200 will
be impacted by an outside object before the tailgate 4 or rear door
of the vehicle 12 is impacted. Also with the step 204 in the
upright position, the brake light 326 is directed rearwardly. Upon
illumination of the brake lights 8 of the vehicle 12, the brakes
light 326 of the step assembly 10 will also illuminate to provided
additional visual warning to following drivers that the vehicle 12
is stopping.
[0106] Finally, with the step 204 in the upright position, a ball
assembly mounted within the brace 212 can be accessed and articles
can be towed using the ball assembly without the need to remove the
step assembly 204.
[0107] To lower the step assembly 204, the user grasps the gripping
ball 350 and pulls, the gripping ball 350 along with the handle 342
outwardly (i.e. to the left). As the user pulls the gripping ball
350, the spring abutment proximate the first spring 344 will cause
the first spring 344 to compress and the right spring bumper 348
will cause the second spring 346 of the release handle assembly 340
to compress. As the springs 344, 346 compress and the tip 356 of
the handle 342 will move to the left of the shaft 206 and the left
side plate 208 of the mounting member 202. Once the tip 356a has
cleared the left side plate 208 of the mounting member 202, the
step 204 is free to rotate about the pivot pin 305. The step 204
continues to rotate ninety (90) degrees until the step 204 reaches
the lowered position as shown in FIGS. 13 and 14. In the lowered
position, the handle 342 is held outwardly, the first and second
springs 344, 346 are compressed, and the tip 356a of the handle 342
contacts the outer surface of the left side plate 208. Rotation of
the step 204 beyond ninety degrees is prevented through contact of
the bottom member 300 of the shaft brace 282 and the bottom surface
of the shaft 306 and the bottom edges of the left and right side
plates 208, 210.
[0108] Rotation of the step 204 beyond ninety degrees is also
prevented through contact of the brace 212 and the front member
256.
[0109] With the step 204 in the lowered position, the stepping
member 322 of the rear member 258 extends horizontally and
rearwardly beyond the lowered tailgate 4 of the vehicle 12. The
stepping member 322 provides a surface preferably approximately
twenty-seven inches wide by twelve inches deep. The user can step
on the stepping member 322 to assist in loading items into the bed
2 of the pick-up truck 12.
[0110] Preferably, the height of the stepping member 322 of the
step 204 is approximately one-half of the height from the ground to
the bed or cargo area 2 of the vehicle 12 or approximately sixteen
and one-half inches from the ground.
[0111] With the step 204 in the lowered position, the user can
activate the switch 332 and the step lights 328 will illuminate the
ground in the area surrounding the step 204 to provide greater
visibility to the step 204 and the surrounding area. In addition,
the swivel mounts 330 allow the user to position the lights 328 and
direct the lights 328 as desired.
[0112] To raise the step 204 to the upright position, the user
simply grasps the rear member 258 and rotates the step 204 about
the pivot pin 305. As the user rotates the step 204, the tip 356a
of the handle 342 slides along the outer surface of the left side
plate 208. The user continues to rotate the step 204 until the tip
356a reaches the bottom edge 230 of the left side plate 208. Upon
rotating the step 204 ninety degrees, spring 346 expands, thereby
pushing against the right spring bumper 348 to force the handle 342
inwardly. The first portion 356 of the handle 342 will extend under
the left side plate 308 and under the shaft 306 of the mounting
member 302 to secure the step 304 in the upright position.
[0113] Unlike the step assembly 10 described above which provides
rotation of the step about the pin 194 which can be positioned
either above or below the shaft 32, the step assembly 200 provides
rotation of the step about the pin 305 which is centrally
positioned within the shaft 206. The step assembly 200 allows
pivoting of the step to occur in an area of low stress. In
addition, the longer left and right side plates 34, 36 are not
necessary, therefore, the step assembly 200 is more compact.
[0114] Attention is now invited to the third embodiment of the step
assembly 400 shown in FIGS. 15 and 16.
[0115] The step assembly 400 is identical to the second embodiment
of the step assembly 200, however, the step assembly 400 includes
additional features. The step assembly 400 is preferably used in
connection with recreational vehicles (RVs). As shown in FIG. 15,
the step assembly 400 includes a generally rectangularly-shaped
step cover 402. The step cover 402 includes a stepping surface 404
and a skirt 406 depending from the left, right and rear sides of
the stepping surface 404. Mounting apertures 408 are provided
proximate the front side of the stepping surface 404. Mounting
apertures 410 are provided in the portion of the skirt 406
depending from the rear side of the stepping surface 404. To mount
the step cover 402 to the remainder of the step assembly 400, the
portion of the stepping surface 404 including the mounting
apertures 408 is placed over the front member 256 of the step
assembly and fasteners 412 are passed through the apertures 408 and
through apertures 414 the front member 256 to secure the step cover
402 to the front member 256. The mounting apertures 410 in the
skirt 406 are then aligned with apertures provided through the rear
member 258 and fasteners are passed through the apertures 410 to
secure the step cover 404 to the rear member 258.
[0116] As shown in FIG. 16, a license plate bracket 412 is provided
on the bottom surface of the step cover 402 for mounting a license
plate thereto. Optional anti-rack bumpers 414 are provided to
engage the bumper to the vehicle. The anti-rack bumpers dampen road
vibrations and remove any play between the step assembly 400 and
the vehicle.
[0117] The step cover 402 provides additional surface on which a
user can step when entering an RV.
[0118] Attention is now invited to a fourth embodiment of the
invention shown in FIG. 17. The step assembly 500 includes a step
cover 502 with a stepping surface 504 and is identical to the step
assembly 400 of the invention with the following exceptions
described below.
[0119] The step cover 502 includes hinges 503, a stepping surface
504, a flange 506, tabs 508, and a latch 510.
[0120] Unlike the step cover 402 which is fixedly mounted to the
remainder of the step assembly 400, the step 502 is hingedly
mounted to the rear member 258 through the hinges 503. More
specifically, first portions of hinges are mounted to the front
panel 316 of the rear member 258 and second portions of hinges are
mounted to the step cover 502. Pivot pins are provided to engage
the first portions of the hinges with the second portions of the
hinges. The hinges 503 allow the step cover 502 to rotate 180
degrees from a first/open position to a second/folded position.
[0121] The flange 506 extends from the stepping surface 504 and is
perpendicular thereto. The tabs 508 also extend from the stepping
surface 504 and are essentially co-planar with the stepping surface
504. The latch 510 is provided on the flange 506 and is positioned
between the tabs 508.
[0122] In the first/open position, the step cover 502 is positioned
proximate the rear member 258 such that the stepping surface 322 of
the rear member 258 and the stepping surface 504 of the step cover
502 are co-planar. In the first/open position, the tabs 508 engage
the front member 256 to provide further support to the step cover
502. In the second/folded position, the step cover 502 is
positioned above the rear member 258 such that the stepping surface
504 rests upon the stepping surface 322.
[0123] In the second/folded position the flange 506 extends over
the rear panel 318 of the rear member 258. A latch 512 can be
provided on the rear panel 318 of the rear member 258 to engage the
latch 510 on the step cover 502. The interengaged latches 510, 512
secure the step cover 502 in the folded position.
[0124] As with the step cover 402 of the step assembly 400, the
step cover 502 of the step assembly 500 provides additional surface
on which a user can step when entering the vehicle. The step cover
502 can, however, be rotated to the second/folded position when the
step assembly 500 is not in use. In this second/folded position,
the step cover 502 is generally aligned with the stepping surface
322 of the rear member 258. Therefore, the step cover 502 is not
positioned to the rear of the license plate and it is not necessary
to relocate the license plate of the vehicle. Rather, the license
plate can be mounted to the rear of the vehicle in the typical
manner. When the step cover 502 is rotated to the folded position
the license plate can be viewed without obstruction.
[0125] While preferred embodiments of the present invention are
shown and described, it is envisioned that those skilled in the art
may devise various modifications of the present invention without
departing from spirit and scope of appended claims.
